Is climate change actually the world's current greatest problem (quite apart from the questions of whether it is immediate or catastrophic)? No seems to be the answer.
If we're going to continue to discover dodginess in the numbers which support the whole climate change things itself then perhaps it isn't a problem at all?
What might be the best mechanism if it is indeed a problem? Governments or markets?
One of those other problems, food for the poor. How not to solve it.
A completely different problem: the recent jump in the US unemployment rate, was it caused by the recent rise in the minimum wage?
That state school/ private school problem. Is it actually worth spending the money on those fees?
And finally, how you don't make people happy by giving them money.
